Here's a new release of SMOB, the Semantic MicrOBlogging framework. This release includes various new features, the main one being the integration of Twitter messages in SMOB so that you can use your SMOB hub as a Twitter client, where each Tweet is represented in RDFa using SIOC, FOAF, etc.
In addition, the new release provides:
sioc:addressed_to annotation);SMOB v2.1 can be downloaded here. If you used a previous version, you will also need to apply this patch after the update. It may remove some of your following / followers (as there have been some changes in the related RDF data - this should be taken into account by the patch, but who knows ...), in that case you'll add to add them again, sorry for the inconvenience !
Hopefully, a 2.2 release will be out in the next weeks, including geolocation of messages, advanced browsing features and other funky improvements. Feature requests can also be suggested on its dedicated bugtracker.
